1 Samuel 12:22-24

For the LORD will not forsake his people for his great name's sake: because it hath pleased the LORD to make you his people. Moreover as for me, God forbid that I should sin against the LORD in ceasing to pray for you: but I will teach you the good and the right way: only fear the LORD, and serve him in truth with all your heart: for consider how great things he hath done for you.
